World number four Rafael Nadal, 36, went in as the big favorite in the quarterfinals against the American Taylor Fritz.
Taylor Fritz, ranked 14th in the world, had never before reached a quarterfinal in a grand slam tournament.
And the Spaniard withstood the pressure, even though it was far from an easy journey.

Nadal won with the numbers 3-6, 7-5, 6-3, 7-5, 7-6.
